To all whom it may concern.:

Be it known that I, GEORGE EDWIN DAG- GETT, of Harrisburg,in the countyof Dauphin and State of Pennsylvania, have invented a new and usefulImprovement in Railroad-Rail Joints, of which the following is aspecification.

My improvement specially relates to a rail-V road-rail joint of a kindwhich comprises an lo angle shoe or chair, a bar of packing materialadjacent to the upright of the chair, a fish-plate at one sideofrail-sectionsto be united, and another fish-plate upon theopposite sideof those rail-sections, all these parts being united by transversebolts. In such a railroad-rail joint and in others having the samegeneral characteristics expansion and contraction are apt to .shift therail-sections in such a Way that instead of forming small zo gapsbetween all the rail-sections the spaces become cumulative' until largespaces are formed between some of the rail-sections, while comparativelynone exist between others.

' 25 The object of the present improvement is to reduce the cumulationof spaces to a minimum. y

This improvement consists in the combination, with various parts forminga rail-joint 3o embodying or resembling the general characteristicsdescribed, ol' bolts having their bodies or portions of their bodiesmade oval or elliptical in` cross-section and applied with the majoraXis or the larger diameter of the elliptical cross-section in asubstantially hori-v tion of the same taken lengthwise of therailsections at the plane of the dotted line 4 in Fig. 2. Fig. 5 is asection of the same taken Fig. 4 is aseo-v lengthwise of therail-sections at the plane 5o of the dotted line 5 in Fig. 2. Fig. 6 isasection of the same taken lengthwise 'of the rail? sections at the planeof the dotted line 6 in Fig. 2. Fig. 7 is a section of the same takenlengthwise of the rail-sections at the plane of the dotted line 7 inFig. 2.

Similar letters of reference designate corresponding parts in all theiigures.

A designates an angle shoe or chair of any suitable material having abase a and an up- 6.o

right c?, preferablyreinforced at their junctional portions.

B and() are fish-plates of any suitable material and constructionarranged upon opposite sides of a rail-section D, which is to be united.to another raiI-sectiOninline with it. E designates a bar of packingmaterial, preferably of wood, arranged intermediate of the upright a2 ofthe angle shoe or chair A and the iish-plate B. F designates bolts, ofwhich there may be any suitable number, extending transversely `thromgfhall the parts named. Each of these bolts has a head e', an oval orelliptical portion e2, adjacent that head and fitting quite closely inan elliptical hole in the upright d2 of the angle shoe or chair A. Themajor axis of this elliptical portion e2 of the bolt and of theelliptical hole inthe upright of the shoeangle is in a horizontal plane.Hence the 8o greatest stilness or strength Aot the bolt is in thatplane; Beyond the portion c2 the body of the bolt e3 is of substantiallyuniform but smaller diameter and still oval or elliptical, and it passesthrough a comparatively large hole in the packing-bar E. The portion e2of the bolt may enter this ,hole in the packing-bar, as shown in Fig. 2.This hole in the packing-bar need not be elliptical.

In the fish-plate B is a hole, whichm'ay be 9o round and lits quitetightly the wider portion of the body e3 of the bolt. v The hole in vtherail-section D may be round. It tits comparativelyclosely the widerportion of the body e3 of 'they bolt. 95 The fish-plate C has anelliptical hole,which may fit quite closely around the elliptical bodye3 of the bolt. The end portion of the bolt e* is cylindrical andscrew-threaded to engage an ordinary nut e5. v y

It will be seen that each bolt will be retained with the major axis ofits elliptical portion in horizontal plan e, and therefore that itsgreater cross-section will be disposed horizontally to give the bolt thegreater strength for resisting strains incident to expansion andcontraction of the rail-section. It will also be seen that theelliptical portions of the bolt tit so closely in the parts with whichthey are combined as to reduce shifting of railsections to a minimum.The fitting of an elliptical portion of each bolt in an elliptical holein the upright of the angle shoe or chair prevents the turning of thebolt.

Nhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination with adjacent 1ailsections and parts applied toopposite sides thereof, of headed bolts passing through all these partsand made oval as to their body portions, said body portions being ofdifferent li-amei ters, and round screw-threaded portions at their outerends, the larger body portions of said bolts being secured by acorrespondinglyshaped hole in one of the parts, so that their 'widestportions Will lie in a horizontal plane and the bolts be prevented fromturning.

f2A The combination with adjacent rail-sec tions and parts applied toopposite sides thereof, of bolts passing through all these parts andmade oval With body portions of substantially uniform diameter, saidbolts being secured with their greatest diameter in a horizontal plane,whereby the spaces between the sides of the bolt and the inside of theboltholes in the webs of the rails are reduced in a horizontal plane, toreduce longitudinal movement ofthe rails.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
